Sounding discussion
An increase in ridging aloft is evident as temperatures have
warmed significantly overnight around 500mb. This has led to an
increase in freezing levels to around 15.5kft, and allowed for a
sharp decrease in lapse rates and overall instability in the mid
to upper levels of the atmosphere. Lapse rates above 850mb are a
low 5.4c km which indicates a relatively stable airmass aloft.

This is also reflected in the low mixed layer CAPE value of only
456 j kg this morning. Below 850mb, a pool of moisture continues
to exist due to sustained southerly flow and some weak low level
instability is also present. With this in mind, most convection
today should be rather low topped. However, with the dry airmass
in place aloft, some gusty winds could occur with these showers.

This is supported by the relatively high dcape value of 877 j kg.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
